LOINC long common name : Liver ultrasound attenuation by transient elastography;
LOINC short name : US.TE Liver attenuation;
LOINC description : A measure of the attenuation of the ultrasound signal (loss of energy) as it travels
through and returns from the liver at 3.5 MHz, often reported simultaneously with
liver stiffness [LOINC:77615-3]. Based on the principle that ultrasound propagation
is affected by tissue fat content, the ultrasound attenuation measurement, referred
to as Controlled Attenuation Parameter (CAP), is a measure of liver fat content (steatosis)
and expressed in dB/m. Increasing steatosis is associated with higher levels of signal
attenuation. [PMID: 22404722];
